安装database driver以连接数据库和pandas以简化Excel写入和数据操作。
$ pip install cx_Oracle pandas
执行以下操作:
import cx_Oracle
con = cx_Oracle.connect('user/password@dsn')
data = pd.read_sql('SELECT * FROM mytable', con)
con.close()
data.head() # take a peek at data
data.to_excel('my_oracle_table.xlsx')

这个答案来自: Python xlwt - making a column readonly (cell protect)
from xlwt import Workbook, Worksheet, easyxf
# ...
# Protect worksheet - all cells will be read-only by default
my_worksheet.protect = True # defaults to False
my_worksheet.password = "something_difficult_to_guess"
# Create cell styles for both read-only and editable cells
editable = easyxf("protection: cell_locked false;")
read_only = easyxf("") # "cell_locked true" is default
# Apply your new styles when writing cells
my_worksheet.write(0, 0, "Can't touch this!", read_only)
my_worksheet.write(2, 2, "Erase me :)", editable)
答案 2 :(得分:0)
感谢Robin Nemeth的回答。我对其进行了一些修改,并获得了所需的输出。
import cx_Oracle
con = cx_Oracle.connect('user/password@dsn')
data = pd.read_sql('SELECT * FROM mytable', con)
data.to_excel('my_oracle_table.xlsx') #called before closing the connection
con.close()
在此处,应在关闭连接之前调用data.to_excel(),否则将导致以下错误“ DatabaseError:DPI-1040:LOB已关闭”。
甚至删除了data.head()函数,该函数不会影响我的输出。
